Mini-Motor

Trojan mini-motors were intoduced as a bolt-on engine to motorise a standard bicycle in 1949. In the post war rationing this device provided an alternative to owning a motorcycle which were still in short supply. Five models were produced, the Mark I to Mark V. Production ceased in 1955 due to a drop in demand.
Trojan experimented with a design for a moped powered by the mini-motor. This was called the "Elswick" Trojan Moped.
